Ubiquitin protein E3 ligase ASB9 suppresses proliferation and promotes apoptosis in human spermatogonial stem cell line by inducing HIF1AN degradation

Biol. Res; 56 (), 2023
BACKGROUND: Spermatogonial stem cells (SSCs) are critical for sustaining spermatogenesis. Even though several regulators of SSC have been identified in rodents, the regulatory mechanism of SSC in humans has yet to be discovered. METHODS: To explore the regulatory mechanisms of human SSCs, we analyzed pub...

Speckle type POZ adaptor protein (SPOP) and its role in cancer

Rev. colomb. cancerol; 25 (3), 2021
Abstract Proteasomal degradation is an essential regulatory mechanism for cellular homeostasis maintenance. The speckle-type POZ adaptor protein (SPOP) is part of the ubiquitin ligase E3 cullin-3 RING-box1 complex, responsible for the ubiquitination and proteasomal degradation of biomolecules involved in...

A novel lncRNA-mRNA-miRNA signature predicts recurrence and disease-free survival in cervical cancer

Braz. j. med. biol. res; 54 (11), 2021
Cervical cancer (CC) patients have a poor prognosis due to the high recurrence rate. However, there are still no effective molecular signatures to predict the recurrence and survival rates for CC patients. Here, we aimed to identify a novel signature based on three types of RNAs [messenger RNA (mRNAs), m...

LncRNA SNHG7/miR-34a-5p/SYVN1 axis plays a vital role in proliferation, apoptosis and autophagy in osteoarthritis

Biol. Res; 53 (), 2020
BACKGROUND: Osteoarthritis (OA) is one of the most common rheumatic diseases of which clinical symptoms includes swelling, synovitis and inflammatory pain, affect patients' daily life. It was reported that non-coding RNAs play vital roles in OA. However, the regulation mechanism of ncRNA in OA pathogenes...

The E3 ligase MuRF2 plays a key role in the functional capacity of skeletal muscle fibroblasts

Braz. j. med. biol. res; 52 (9), 2019
Fibroblasts are a highly heterogeneous population of cells, being found in a large number of different tissues. These cells produce the extracellular matrix, which is essential to preserve structural integrity of connective tissues. Fibroblasts are frequently engaged in migration and remodeling, exerting...

PELI3 mediates pro-tumor actions of down-regulated miR-365a-5p in non-small cell lung cancer

Biol. Res; 52 (), 2019
BACKGROUND: To analyze the relative expression of PELI3 and its mechanistic involvement in the non-small cell lung cancer (NSCLC). Methods: PELI3 expression in NSCLC tissue samples was determined by the immunohistochemistry. The transcripts abundance of PELI3 was measured with real-time PCR. The protein...

The role of vitamin C in the gene expression of oxidative stress markers in fibroblasts from burn patients

Acta cir. bras; 33 (8), 2018
Abstract Purpose: To assess the action of vitamin C on the expression of 84 oxidative stress related-genes in cultured skin fibroblasts from burn patients. Methods: Skin samples were obtained from ten burn patients. Human primary fibroblasts were isolated and cultured to be distributed into 2 groups:...

Protective roles of autophagy in retinal pigment epithelium under high glucose condition via regulating PINK1/Parkin pathway and BNIP3L

Biol. Res; 51 (), 2018
BACKGROUND: Our study aimed to investigate the roles of autophagy against high glucose induced response in retinal pigment epithelium (ARPE-19 cells). METHODS: The morphological changes and reactive oxygen species (ROS) generation in ARPE-19 cells under high glucose treatment were respectively detected u...

Overexpression of UHRF1 gene correlates with the major clinicopathological parameters in urinary bladder cancer

Int. braz. j. urol; 43 (2), 2017
ABSTRACT Introduction Recently, expression of the UHRF1 gene was found to be up-regulated in numerous neoplasms, including the urinary bladder transitional cell carcinoma (TCC). Objective The aim of our study was to determine if the expression levels of UHRF1 gene correlates with the major pathologic...
